PREPARATION METHOD OF MATAL NANO POWDER WITH NARROW PARTICLE SIZE DISTRIBUTION AND EXCELLENT DISPERSIBILITY, METAL NANO POWDER PREPARED THEREFROM AND A METAL INK COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: A preparation method of metal nano powder is provided to prepare metal nanoparticles by introducing proper reducing agent and dispersing agent through a wet reduction process.;CONSTITUTION: A preparation method of metal nano powder comprises the steps of: (i) neutralizing metal precursors and fatty acid hydrocarbon having carboxyl groups in a solvent to form fatty acid metal salts; (ii) dispersing the fatty acid metal salts with a dispersing agent in a solvent to prepare a suspension; and (iii) adding a reducing agent to the suspension, and reducing and segregating metal to obtain metal nanoparticles.;COPYRIGHT KIPO 2011
